Final answer:
The decrease in the number of olfactory neurons as we age can impact the detection of warning smells like gas leaks.

True. As we age, the sense of smell diminishes due to the decrease in olfactory neurons' ability to replace themselves, leading to age-related anosmia. This reduced sense of smell can impact the detection of warning smells like gas leaks, making it more challenging for elderly individuals to notice dangerous situations.
